By definition the area of a rectangle is:
A = l * w
Where,
l: long
w: width
So we have to clear the width:
w = A / l
Substituting the values:
w = (234) / (18) = 13
w = 13 feets
answer
the width, in feet, of the room is 13

Answer with negative exponent = 
===========================================================
Explanation:
The rule we use is

If we multiply two exponential expressions with the same base, then we add the exponents.
The base for each is 5. The exponents 4 and -7 add to -3.
This means

To convert to a positive exponent, we apply the reciprocal to the base. We go from 5, aka 5/1, to 1/5.
So, 
Answer:
(n-14) / n
Step-by-step explanation:
n is your number;
"14 less" means "subtract 14", --> we have (n-14);
now we need to divide (n-14) by same number as your number, which is "n"---> final expression is: (n-14)/n
